Jason Miller, Donald Trump's campaign spokesman, Wednesday said he and the president-elect's son-in-law Jared Kushner have been "chuckling" about CNN's reports of a "knife fight" within the presidential transition team, and denied reports of trouble with the process.

"Jared and I were chuckling about it this morning — this whole description of the knife fight or this internal fighting," Miller told CNN's "Newsroom with Carol Costello" program, Wednesday morning. "Nothing could be further from the truth."

Kushner, who is married to Trump's daughter Ivanka, is helping with the transition, Miller continued, but Trump himself will have the final say over who is hired.

"He's going to make sure that we have the absolute best people," Miller continued, and some of those people will not come from the political world.

Miller also denied reports Trump had sought security clearance for any of his children. His three oldest, Donald Jr., Eric, and Ivanka, are part of the transition team, as is Kushner.

Miller, appearing earlier on Fox News' "Fox & Friends," said Trump is working hard to "get this right."

The story continues after the video.

"He's going to make sure that every single appointment and every single person he puts into key leadership is someone who is absolutely top-notch leadership, who has a good track record, [and] who's going to help him implement his agenda," Miller said. "The president-elect, working with Vice President-elect [Mike] Pence, they have a very systematic plan to get things put in place. They want to make sure that everything is put together right. We don't want to get in there and have any false starts or stumbles."

Sen. Ted Cruz has been one of many people seen going into Trump Tower for transition meetings, but Miller would not say if there are plans to include him in a Trump administration.

"Sen. Cruz came on board during the campaign, and we're glad to have his support," said Miller of the senator, who fought bitterly with Trump during the campaign and who held out on supporting him for some time. "He's a great ally. He's offered to help as we're putting things together. I think he's someone that would be a big asset going down the road."

Cruz, he continued, "is definitely someone who has some very good ideas for how to structure the government going forward."

On CNN, Miller also defended Trump's choice of former Breitbart CEO Steve Bannon as his chief strategist, insisting he is a strong Zionist and to refer to him as being anti-Semitic or a white supremacist is "silly."

"If you can see the internal workings of the campaign, [you would] see that Steve Bannon is someone who pushed for diversity at every turn in the campaign, that he is one of the driving forces in having the president-elect go to Mexico on that trip and to meet with [Israeli Prime Minister Benjamin] Netanyahu," Miller said. "Ultimately, Steve Bannon is going to implement the plans and the agenda of the president-elect. And he did a fantastic job of doing it during the campaign."
